To all whom it may concern:

Be it knovm that I, JOHN JonNs'roN, a

citizen of the United States, residing at the shuttle is provide'dwith a hand threading device of a sim le and durable construction adapted to' facilitate the threading of the shifitle by hand without suction.

Y novel construction of the delivery end of a loom shuttle and mechanism for guiding the thread to the delivery e e in threading the shuttle by hand, as wil be more fully'set forth hereinafter and claimed.

p Figure 1 is atop plan view'of the thread delivery end of my 1111 roved loom shuttle.

' Fig. 2 is a side view of t e delivery end of the shuttle, looking at" the delivery eye side.

Fig. 3 is a longitudinal sectional view through] 1 the delivery end of the shuttle taken on line 33ofFig. 1. I

view through the shuttle taken on line 4 4 of Fig. 1. Fig. 5 is a longitudinal detail sectional view through'the threading mechanism of theshuttle, taken on line 5 5 of Fig. 2,

- and Fig. 6 is a side view of the split pin forming the guide eye of the shuttle.

n the drawings, a indicates the thread deliverv end of a loom shuttle, b the bobbin, 0

the bobbin cavity, (1 a circular depression in the top of the shuttle adjacent the end of the shuttle, e a vertical slot extending lengthwise from the shuttle cavity 0 into the depression d and out through the top of the shuttle, f a vertical slit extending longitudi- -nally in the bottom of the slot e, g a vertical groove in the side of theslot e bobbincavity c, h a longitudinal groovein the eye side of the slot e, i a round vertical. hole extending from the top of the shuttle downwardsand intersecting the slot e and the groove h, 'k a curved longitudinal recess in the eyeside of the shuttle intersecting thev transverse slit extending vertical hole i, Z a

curved recess it, an a threading plate and n a split pin forming the guide eye of the shuttle.

The threading plate m is constructed pref erably of sheet metal wi'th'dies shaped to form a fiatbodyhaving a base 7, apointed no arm 8 forming an extension of the top, a central circular opening 9 at the intersection. of the arm 8 With the base 7, two tongues '10 10 extending out from the face of the plate at an angle toward each other on a horizontal line adjacent the top, a tongue 11 extending downwardly at an angleifrom the back of the plate, and two holesl2 12 in the base 7, as shown in Figs. 3 and 4.

The split pin 07. has end 13 and the longitudinal slit 14 extending from the V-shaped end downwards, as shown in'Fi 6. Y

In operative position the threading plate 1 m is placed in the depression g1, and the base 7 forced into the slit f in a positionto bring the end of the pointed arm 8-into the depression (1, the tongues 10 10 into the horizontal groove h, the tongues 11 into the ver-' tical groove g,

cured by pins 15 15 driven into the shuttle through the holes 12 12 in the plate m. The] split pin it is now vertical hole 1'. in a position for the slit 14 in the pin to coincide withthe slit 1 in the shuttle, as shown in Figs. 1 and 2.

In threading up the shuttle the thread is carried from as shown in pressed into the depression (1 and brought I under the'pointed arm 8 of the threading late m, as shown in heavy dotted lines, then into the space between the threading late m and the wall of the slot 6 through the mi 95. zontal groove h by the tongue 10 on the arm: Sand under the arm 8, and then through the slit Z in the shuttle, whichlbrings the thread under the tongue 11 on the' late .m and out through the opening 'slit 14 in the pin 11. and the recess'kin the shuttle, as shown in Figs. 1, 2 and 5. The thread is now prevented from returning by the tongues 10 10 and 11 on the threading plate'm. Having thus described my inventiom yl claim as new and desire to secure by Letters Patent 1. A shuttle body formed to have a depression in theV-shaped upper 70 and the opening 9 on a line 80,. with the vertical hole i in the shuttle and se.

driven downwards into the i thebobbin'b through the slot e, 1 light broken lines in.Fig'. 1-, then v .90

9 in to plate m, the' loo' ice the top of the delivery eye end. a

longitudinal slot extending from the bobbin cavity to the depression and out through the top, a longitudinal slit in the bottom of the slot, a vertical groove in the side of-the slot, a

longitudinal groove in the side of the slot, a

recess in the side of the shuttle, a transverse slit extending from the top of the shuttle downwards and intersecting the longitudinal groove and the recess, a vertical hole ex- [fending downwards from the top of the shutthe shuttle in a position to bring the end of a the pointed arm in the recess in the top of the shuttle, two of the tongues'in'the longitudinal groove in the shuttle and one tongue in the vertical groove in the shuttle, and a split pin in the vertical hole in the shuttle forming the guide eye of the shuttle.

2. The combination with a shuttle body cavity a, a circular de ressi'on (Z in the to a vertical slote exten ing from the bob in cavity 0 into the depression (Z, and out through the to of the shuttle, a slit f in the bottom of the s ot e, a vertical groove 9 in the side of the, slot 6, a longitudinal the side of the slot 6, a vertical hole 11 extending from the top of the shuttle downwards, a recess 70 in the side, and a transverse slit Z, of a threading plate m having a base 7, a pointed arm 8, a central opening 9, two tongues 10 10 on the face of the plate, a tongue 1 1 on the back of the plate, and a s lit pin n having a V-shaped end 13 and a s it 14 forming the guide eye of the shuttle, as described.

In testimony whereof I have signed my name to this specification in the two subscribing witnesses.

JOHN JOHNSTON.
